TANGLEWOOD WS is one of 1,060 community water systems in Colorado in the 500 or fewer people size category, serving 60 people from groundwater.
As of August 1, 2026, its federal record holds 8 entries between 1992 and 2007, all of which EPA lists as closed. Nothing has been added since 2007.
Of the 8, 7 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves the Stage 1 Disinfectants and Disinfection Byproducts Rule, inorganic chemicals, and the Total Coliform Rules.
